To all whom it may emanate 2 Be it known that I, UHARLES A, Jenner, :1"itizen of the United States, and resident oi Jryse, in the county ofEstill, and State of Kentucky, have invented certain new and usefulImprovements in a Continuous trolenm-Refining Apparatus, of W'iieh thefollowing; is sifJeeilioetioni The present inventioi'i relates to therelining of oils sneh petroleni'n, end relates more particularly to onimproved process; and, appointee for producing this;

:lonnd hy iuituel pine-the thet the preeent proeessee and emiemtne forrefining petroleum are very woeteiul end externgent not (oily in theeoneiunntion of fuel hut also in the etqnieity of the epperotnsemployed. The preeti 'nl stills employ are arranged lengthwise in ahorizontal po ion and ore connected from one to the othe 1' so that theymay be operated in oontinntuie manner. This is known in practice as econtinuous still and the tanks or eontoiners n'met he tilled to hell. oftheir capacity to ohtein maximum eflie'iene oi the apparatus. There isthus only titty per tent of the in ternel space IPlnitlfllllg tor theeeentmiletion of the vapors, end it is essential to maintain e very hotlire against the under sides oi? the i'enits for thoroughly heating therelatively large solid masses of fuel in the lower halves of the tanks.

It is therefore the object of the present invention to provide :1continuous still which ii: so or mined that 2: small volume ot heet outhe utilized in the heating of the various einn mrtniente or rhouiheirsoi? the stil s end wherein it relatively small proportion oi oil it:brought into intimate eonteet in :1 reletii el thin. snrinee eooting'oithe oil with n heating; medium to insure the exmporetion oi the oil in ereletively short time; to utilize the heat which heretofore has been.elloi'ved to eeenpe; to provide se orote eon tu'irtinente for therolntilimtion oi the i'oi'overed oil and four independently regulut ing;the limiting of the compartmentsi end to provide means for recoveringthe oil eondonsing before final. separation.

The pr sent invention also pro'videe for treating the vapor to grade anddist-ril'inte the oil, and to mainteil'i the various desiredtemperatures of the oil for producing the Serial, to $855,331.

The main portion of the apparatus which may he herein termed as thestill is arranged within and supported upon the stack 13. and comprisesa plurality of superposed chombers or tanks 22, o tank being arranged ineach compartment 01": the stack and adapted to fit snugly against theinwardly tending partition flange 14- therco'f to pro- "ride a.substantially sealed annular chamber in the stack about each of thestill chambers.

The heating mcdilun thus entirely surrounds the still chambers and arelatively lor re heated surface area. is thus provided.

An oil receiving and heating coil is suitably arranged in the coilreceiving chumher 12 of the turnecerand preferably has an inlet 24 htthe upper end of the coil. and an outlet pipe 25 leading from the lowerend of the coil and extending to the top of the still. The uppercompartment 22 of the still has therein a distributing rose or member 26which is in communicotlon with the pipe 25 to receive oil therefrom, thedistribn'ting member 26 having downwardly directed openings for sprayingthe heated oil or vapor downwardly through the upper compartment 22. Theit per compartment 22 is provided with a. re ielly inclined bot tom 2?and is provided. it the marginal edge of the bottom with atsubstantially annuler slot or opeping 28 though which oil lowing overthe bcttom El? may escape into the subimposed compartments. Supportedupon the bottom 2? is a preheating coil 29 adepted to the tempereture ofoil. felling upon the bottom 2? and sseist in vaporizing the some. Fromthe marginal edge of the. bottom 2'2 there depends an annular row ofpipes .30 spaced concentrically inward from the plane of the. outer wallof the comper rnent and adopted to project down into an. annular uformed between. the inner illend of the subimposed and outerwcompartments. The pipes 50 terminate short of the hot-tom or the saidspace of the enbjocent compartments and form therein traps for holdingand collecting" the dripr nners ping; oil from the bottom 27 of theupper 00hr pertinent against the outer wall of the lower compartment.The outer well 32 oi the lower compartment provides a heating surface.over which the relatively thin film of oil passes. the oil beingvaporized and directed by the trap pipes into the space between the sameand the inner well ll, and into the lower compartment. The vapors whichthus enter the top of the lower or second compartment :1 re trappedtherein and any condensate resulting therefrom falls upon the bottom 27of the second co1upertinent. trorn which the oil passes into the thirdcompartment as above forth. he action is similar throughout the varioussuperposed compartments employed in the still.

As shown in Fig. 5?. the damper 18 from the flue 15 to the heatingchamber surrouruling' the second conumrtment is closed. When this isopened. the products of com bustion pass from the flue 15 into the anonlur passage and raise the temperature of the second still con'i nirtmentto the desired degree for vuporizinc the oil at the requiredtemperature.

Opening into the top of the chamber 932 is a vapor receiving pipe 33adapted to con-- duct the vapors accumulating in the upper end of thecomportn'ient 22 to corresponding compartments in a vapor treating towerer ranged preferably ndpicent to the stack: 13. The vapor treating towercomprises 9. plurality of superposed sections 34 corresponding in numberand height, preferably, to the number and height of the compartments ofthe still. Each compartment 34 is provided with spaced-sport perforateddiffusing discs 35 downwardly over and through. which the vapor isadapted to pass, and which supports 3 preferably centrally arranged heatdistributing pipe 36 provided with radial openlugs therenbout fordelivering jets of steam to the downwardly moving vapor above, betweenand below the diffusing discs 35 for thoroughly impregnating the vaporand increasing the heat to the desired saturation point. The treatedvapor passes from the .ower end of each compartment 34 through a pipe 37into the lower end of e correspond ing compartment 38 of the rock tower.The pipe 37 opens into the lower end or the compartment 38 in slightlyspaced relation to the bottom thereof to admit the accumulation ofcondensate otthe lower end of the compartment or chamber 38. The returnpipe 39 leads from the bottom of the corn-- pertmcnt 38 to thecorrespondiujy subjs cent chamb r of the still tower ibr returning thecondensate t the tower to be reveporized and subsequently treated asabove. set forth. The return pipe 3!) is .referebly provided with o trap40 therein tor sealing the pipe 39 against the passage of vapor ans eefi'omthe subjaoent ehembr 22 directly into tion it will he noted thatpercent ol the spore within the the roclr tower.

Each compartment 38 of the reek to'wer is provided with a plurality ofsuperposed perforated discs t], adapted to sup wort suitable filteringsubstances, such as rorlr ground to the dei iired fineness. Asillustrated in Fig.- 4, the masses of rock {r2 upon iomminous (liars,and the vapor, enhseqnent to their preheating, pass upwgndly through thevarious filtering HUM-A308; for my traetingi; forei nsuhstuncea from therapor and thorough y ,aclmixin the vapor with the steam, the vapor prosuetii being! carried from the upper endof the compartment 38 through adelivery pi )e 43*, which may he connected to a snitabe eondeneerof anywell-known type. 'lhezsteainpipos 29 and 36 may be connected to anysuitable source a 5 of Steam, such as to a common 4,4, and anycorresimnding number of coinpartments or rhmn iere may he employed inthe still. and thetim'ere eminent-ed thereto supply pipe tor producingthe desired number of grades of o1l,,the lower compartment yielding aheavier grade ()fnil, and the product from which may be converted intolubricating and cylinder oils by the treatment of the residmun in theordinaljv lulu-mating still.
